NEW YORK, N. Y.

MECHANICAL MOVEMENT.

PECifliICZ-XTION forming part of Letters Patent No. 339,987, dated April13, 1886.

VApplication filed January 15, 1586. Serial No. 1851,68?. (Nonlodcl.)

To @ZZ whom, it may concern:

Be it known that I, OTTO HUEELAND, a citi zen of the United States.residing at Hount Vernon, iu the county of Westchester and State of NewYork, have invented new and useful Improvements in Mechanical Movements,of which the following is a specication.

This invention has for its main object to provide novel and eiicientmechanism for moving a. sewing-machine shuttle in a rectilinearshuttle-race, but the invention is applicable for other purposes.

This invention consists in the combination, with a lever and itsfulcrnmpin, of a movable support for the fulcrumpin, guides for thesupport, constructed to retain said pivot in a rectilinear path, anoscillating arm, a pivotal connection between this arm and the lever, arevolving` shaft, and suitable connections between the arm and theshaft; so that by imparting to the arm an oscillating motion within theproper limits the free end of the lever is caused to move in a straightline. Vith the lever and the oscillating arm is further combined acarriage pivoted to the end ofthe lever and a connecting-rod pivoted atone end to the carriage andV at its opposite endY to the Oscillatingarm, so that the position ofthe carriage during its motion is governedby the oscillating arm and the lever.

In the accompanying drawings, Figure 1 represents a front view. Fig. 2is a side view.

Similar lettersindicate corresponding parts.

In the drawings, the letter A designates a lever, which has its fulcrumon a pivot, a. In the example shown in the drawings this pivot issecured to a slide, b, which moves in rectilinear guides c c,- but otherwell-known means may be substituted for retaining the pivot a in arectilinear path.

B is an arm, which is connected to the lever A by a pivot, d, and whichis mounted on one end of a rock-shaft, e, to the opposite end of whichis secured an arm, C, the end of which engages with a lever, D. Thislever has its fulcrum on a stud, f, and it carries a rollerstud, q,which engages with a cani, E, mounted on a shaft, F, to which arevolving motion is imparted by any means suitable for the purpose. Itis obvious, however, that the connections between the shaft F and theoscillating arm B can be modified, as will readily suggest itself to anyskilled mechanic. By revolving the shaft F an oscillating motion isimparted to the arm B within fixed limits, and the free end ofthe leverA is moved in a straight line. If the oscillating arm should be lnovedbeyond said fixed limits, the free end of the lever A would depart froma straight line.

G is a carriage, which is connected to the free end ofthe lever A by apivot, g, and this carriage connects by a rod, H, with the oscillatingarm B, one end of said rod being attached to the carriage by a pivot,t', and to the arm I3 by a pivot, L. The position of the carriage inrelation to the lever A and its movement depends upon the distance ofthe `pivot i from a line, j k, drawn through the pivot g at right anglesto the lever A and upon the distance of the pivot h from the pivot d. Ifthose two distances are alike, the carriage will move in a rectilinearpath, and will be held in a position parallel to its originai positionthroughout the entire movement of the lever A, as indicated in dottedlines in Fig. l. In this figure the bottom line of the carriage isparallel to the path in which it moves; but said bottom line may be atan angle to said path. If the distance between the pivotz'and the linejk is greater or less than the distance between the pivot 7L and thepivot d, the carriage will oscillate on its pivot g during the motion ofthe lever A from one end of its stroke to the other.

In the example shown in the drawings, an additional connection, H', isshown between the carriage and the oscillating arm B. This additionalconnection, however, is only required if both connections I-I and H aremade of a tiexible material, such as cord.

X/Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the lever A and its fulcrum-pin a, of a movablesupport for the fnlcrmnpin, guides for this support, constructed tocompel said support to move in a straight line, an oscillating arm, apivotal connectiou between this arm and the lever A, a revolving shaft,and suitable connections between said arm and the shaft, substantiallyas shown and described.

In testimony whereof I have'hereuntoset my hand and seal in the presenceof two'sub- 3o scribng witnesses.
